Why the transmitter channel cannot be set with infrared transmission on Sony Microphone system?

  Ernest MitchellSep 8, 2025
  If you cannot set the transmitter channel with infrared transmission on your Sony Microphone system, reduce the distance between the infrared receptor on the transmitter and the infrared transmission port on the tuner to within about 20 cm (8 in.). Also, place the transmitter and tuner as close to each other as possible to avoid interference from other devices or direct sunlight.

  Curtis LambertAug 23, 2025
  If your Sony Microphone system isn't producing any sound, make sure the channel setting on the transmitter matches the tuner. Confirm the transmitter is on and reduce the distance between it and the tuner if the transmission output is weak. Ensure the transmitter is set to microphone input, not line level. The compander mode setting on both devices should be the same. Also, check if the transmitter is muted and change the MUTE SETTING if it is set to PTT HOLD.

  If your Sony Microphone system is not turning on, ensure the batteries are inserted with the correct polarity. Replace low batteries with new ones. Clean any dirt from the battery terminals and the battery compartment with a cotton swab. If using battery power, make sure batteries are inserted and the power source is set to 'BATT ONLY'. If using the SMAD-P5, check that it is correctly connected to the camera or tuner and that the power supplies for the tuner and camera are correctly linked.

  If there is no sound from your Sony Microphone system, verify that the channel setting is the same on both the transmitter and tuner. Confirm that the transmitter is on and reduce the distance between the transmitter and tuner. Ensure the transmitter is set to microphone input, not line level. The compander mode setting must be the same on both devices. Check if the transmitter is muted and release it by pressing the POWER/MUTE button. Review the MUTE SETTING menu and audio output connector settings. If using the SMAD-P5, ensure the Analog/Digital switch is correctly set. For microphones connected to the MIC INPUT, configure the microphone setting in the MIC SELECT menu to match the microphone type.

  To resolve the issue of louder noise when connected with SMAD-P5 compared to the XLR-BMP conversion output cable on your Sony Microphone system, adjust the reference input level and reference recording level of the camcorder, or adjust the OUTPUT LEVEL on the tuner to set the appropriate audio level.

- C
  Claudia LiAug 30, 2025
  If the sound from your Sony Microphone system is weak, the attenuation level on the transmitter might be too high; adjust it to an appropriate level. Also, check the volume on the amplifier or mixer and adjust it accordingly. Ensure the transmitter is set to microphone input, not line level. The compander mode setting on the transmitter should match the one on the tuner.

Why is the sound distorted on my Sony UTX-P40?
- A
  Amber MartinSep 10, 2025
  If the sound from your Sony Microphone system is distorted, the attenuation level on the transmitter might be too low or set to 0. Adjust the attenuation so that the audio is not distorted. If the GAIN MODE menu is set to 15dB BOOST, change it to prevent distortion. Ensure the channel setting is the same on both the transmitter and tuner. Use headphones with a stereo mini jack. If the OUTPUT MODE menu of the tuner is set to HIGH GAIN, change it to NORMAL. If the distortion occurs when using a microphone connected to the MIC INPUT connector, configure the microphone setting in the MIC SELECT menu to match the microphone type.
